The additional percent that a median female bank teller earn than a median male bank teller in 1969 was 8.5% (to the nearest tenth of a percent)

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Female bank tellers median earnings in 1969 = US$ 4,190

Male bank tellers median earnings in 1969 = US$ 3,860

2. How much more did female bank tellers earn than male bank tellers as a percentage of male bank teller median earnings in 1969 (to the nearest tenth of a percent)?

For answering the question we will use the following formula:

Additional percent that a median female bank teller earn than a median male bank teller in 1969 = Female bank tellers median earnings in 1969/Male bank tellers median earnings in 1969 - 1

Replacing with the real values, we have:

Additional percent that a median female bank teller earn than a median male bank teller in 1969 = 4,190/3,860 - 1

Additional percent that a median female bank teller earn than a median male bank teller in 1969 = 1.085 - 1

Additional percent that a median female bank teller earn than a median male bank teller in 1969 = 0.085 = 8.5%

The additional percent that a median female bank teller earn than a median male bank teller in 1969 was 8.5%
